The evidence files
A remembered version, a documented detail, and a way to investigate each claim.
These case files pair our memory tests with source checks you can repeat. Each separates the detail established by a record from our interpretation of why an alternative may seem familiar. They do not assume that a vivid memory is dishonest, or that a surprising answer proves a change to reality.

Bring a source, not just a screenshot
Useful evidence identifies the original object, date, country, edition, and where it can be inspected. A parody or printing error may be interesting, but it answers a different question from an official title or standard design. Read our editorial standards or send a correction.
